What is CefSharp.BrowserSubprocess.exe – CefSharp.BrowserSubprocess.exe is a legitimate background process used by applications that embed a Chromium-based browser through the CefSharp framework. It handles tasks like rendering web pages and running scripts, ensuring the main application stays responsive. While safe, malware can sometimes disguise itself with similar names, so verifying its location and signature is important.
How CefSharp.BrowserSubprocess.exe Works
- Part of CefSharp: CefSharp is a .NET wrapper around the Chromium Embedded Framework (CEF).
- Role of BrowserSubprocess: It runs as a separate process to handle web rendering, JavaScript execution, and other browser tasks.
- Keeps apps stable: By offloading these tasks, the main program avoids freezing or crashing.
Why You See It in Task Manager
